A kind of multi-station machine tool
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of lathe, particularly a kind of multi-station machine tool.
Background technology
At present, known lathe only has a kind of function mostly, only has the function of milling as milling machine, and it can only do the circumference rotary cutting, and the independent use procedure that can only finish part, can not carry out side processing to part simultaneously.Bore in the process mill at metal, usually can run into that to need machining shape complexity, class shape to relate to more, the part that required precision is high is again processed this class part, often needs just can finish through several milling machines processing.Owing to use milling machine instead, cause each clamping all can produce the accumulative total position error, cause the round conveying of reductions of workpiece machining accuracy, percent defective height, each inter process that the production cycle is grown, production efficiency is low, working strength of workers is big, input cost is high.This class milling machine function ratio is more single, and automaticity is low.
Advanced at present is to adopt building-block machine to unite processing. but because present each cutting head of existing building-block machine adopts independent feeding, and each cutting head spindle number is limited, wheelbase is bigger, can't once finish intensive similar operation on same station.Like this, though improved work efficiency than streamline, because multiple clamping, precision can be difficult to guarantee, and equipment investment is also big, and production cost is still higher.
For this reason, people have proposed various solutions through long-term exploration, and some has also applied for patent.For example Chinese patent discloses a kind of numerical control multistation machine tool [Granted publication CN 2552633Y], and circular index dial is housed on the lathe, and the instrument folder is housed on the index dial, in the corresponding position of instrument folder workbench is housed on the support, and microcomputer also is housed on the support.This numerical control multistation machine tool can be finished fraising, milling simultaneously, be holed, attacks spiral shell work, perfect in shape and function, high efficiency, automaticity height, the steady quality of part processing.
But this numerical control multistation machine tool still exists following shortcoming: 1, cutting head spindle is more, is installed to take on the lathe than large space, causes lathe enough just can hold more main shaft greatly; 2, whole machine tool structure complexity, inconvenient operation needs the plenty of time to the workpiece location, and operating efficiency is low; The long service life of 3, lathe cost height, and lathe has increased processing cost.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, proposed a kind of simple in structure, the multi-station machine tool that can carry out processing such as milling, flank hole, reaming simultaneously.
The purpose of this utility model can realize by following technical proposal: a kind of multi-station machine tool, comprise a lathe bed, described lathe bed top has headstock and guide rail, be connected with the carriage component of translation thereon on the guide rail, it is characterized in that, be connected with unit head by a dismountable bindiny mechanism on the described carriage component, have actuating unit and the cutter that links to each other with actuating unit on the described unit head.
Be provided with the anchor clamps of energy clamping work pieces on headstock, in the process of processing work, control system control carriage component moves to the workpiece direction along guide rail in the Digit Control Machine Tool, and carriage component is driving unit head and moving together.When moving to cutter and workpiece fit position, actuating unit drives cutter workpiece is processed.Make carriage component and cutter move according to machining path in the process, machine rear rail drive carriage component and return.This lathe medium power head can also can be parallel to workpiece setting perpendicular to workpiece setting, guaranteed like this can be on same lathe the end face of processing work and the side of workpiece simultaneously.
In above-mentioned multi-station machine tool, described bindiny mechanism comprises along the locating slot of carriage component horizontally set and is through at the dog screw that the unit head bottom is located, dog screw can be connected in any position of above-mentioned locating slot, and the main shaft of above-mentioned unit head is parallel with guide rail.
By dog screw unit head is positioned on the locating slot, and locating slot is along the carriage component horizontally set, so unit head can be installed in the optional position on the carriage component according to the needs of workpiece processing.And the main shaft of unit head is parallel with the face that guide rail is in, and can guarantee that like this cutter is vertical with workpiece, at this moment the side of processing work; Can guarantee that also cutter is parallel with workpiece, at this moment the end face of processing work.
In above-mentioned multi-station machine tool, described bindiny mechanism also comprises the dog screw that is through at place, unit head end, and dog screw can be connected in any position of above-mentioned locating slot, and above-mentioned dynamic head main spindle is vertical with guide rail.
The purpose of She Zhiing is like this, and unit head vertically is provided with, can be to the punch processing of reaming etc. of workpiece.As the case may be dog screw is connected in certain location on the locating slot, with convenient processing to workpiece.
In above-mentioned multi-station machine tool, described unit head is by support and be positioned at motor on the support, driving-belt and main shaft etc. and form, and above-mentioned driving-belt is enclosed within on machine shaft and the main shaft, has the chuck that is used for the clamping cutter on the main shaft.
In process, motor rotates and drives driving-belt, and driving-belt drives main shaft, has the chuck that is used for the clamping cutter on the main shaft, and main shaft rotating band moving knife tool rotates, thereby realizes the processing to workpiece.
In above-mentioned multi-station machine tool, the quantity of described main shaft is 25.The purpose of She Zhiing is and can carries out porous processing to workpiece simultaneously like this, is provided with as the case may be, and the quantity of general main shaft is 2.
Compared with prior art, this multi-station machine tool has the following advantages:
1, simple in structure, easy to operate, the workpiece machining accuracy height of this machining tool, and percent defective is low, production efficiency is high, the cost of input is low.
2, can carry out the circumference rotary cutting to the end face and the side of workpiece simultaneously, and can also hole to workpiece, reaming and side tapping, powerful, this lathe links to each other with digital control system, the automaticity height.
